ABSTRACT
Objective To study the efficacy of tirofiban coronary injection combined with atorvastatin in the treatment of patients with acute coronary syndrome (ACS) and arrhythmia. Methods Ninety-two patients with ACS and arrhythmia admitted to Yiwu Central Hospital from January 2017 to May 2018 were enrolled, and they were divided into a control group and a study group by reference to random number table method, with 46 cases in each group. The patients in the control group received routine treatment; the patients in the study group were treated with tirofiban coronary injection combined with atorvastatin on the basis of the treatment in the control group. The changes of myocardial injury markers, blood lipid levels, inflammatory factors, apoptosis indicators and incidence of adverse reactions were observed before and after treatment in the two groups. Results After treatment the levels of serum cardiac troponin T (cTnT), creatine kinase (CK), CK isoenzyme (CK-MB), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), interleukin-6 (IL-6), hypersensitive C-reactive protein (hs-CRP) and C-myc were significantly lower than those before treatment in the two groups, and all the levels in the study group were lower than those in the control group [cTnT (mg/L):1.5±0.5 vs. 3.2±1.0, CK (U/L): 158.6±17.2 vs. 224.1±20.3, CK-MB (U/L): 30.5±11.4 vs. 44.3±9.7, TC (mmol/L):5.0±0.8 vs. 5.6±0.5, LDL-C (mmol/L): 2.0±1.0 vs. 2.7±1.3, IL-6 (mg/L): 86.5±15.2 vs. 131.4±16.3, hs-CRP (mg/L): 4.7±3.3 vs. 7.3±3.6, C-myc: (18.2±8.1)% vs. (23.4±10.3)%], and all the above differences were statistically significant (all P < 0.05). After treatment, the levels of Bcl-2 in the two groups were significantly higher than those before treatment, and the level in the study group was obviously higher than that of the control group [(78.4±12.2)% vs. (69.3±9.7)%, P < 0.05]. The adverse reactions were found in 6 patients in each group, and the incidence of adverse reactions was the same in the two groups [13.0% (6/46) vs. 13.0% (6/46), P > 0.05]. Conclusions Tirofiban coronary injection combined with atorvastatin is markedly effective in the treatment of patients with ACS and arrhythmia, as it can reduce myocardial cell damage, regulate blood lipid levels, inhibit inflammatory response and antagonize cardiomyocyte apoptosis.
ABSTRACT
Objective To observe the efficacy and safety of tirofiban combined with lowmolecular-weight heparin in treatment of acute coronary syndrome.Methods 138 patients with acute coronary syndrome were divided into two groups(observation group and control group).In observation group,80 cases were treated with tirofiban combined with low-molecular-weight heparin on the basis of conventional therapy.In control group,58 cases were treated with low-molecularweight heparin on the basis of conventional therapy.The efficacy and safety were compared between the two groups.Results The total efficacy was higher in observation group than in control group (x2=8.589,P＜ 0.01).The improvement of 24 h anginal attacks,decrease in values of ECG ST segment and cardiac troponin T value were better in observation group than in control group(all P＜ 0.05).The blood platelet count and adverse reactions were not different between the two groups(t=0.294,x2 =0.747,both P ＞ 0.05).Conclusions Tirofiban combined with low-molecular-weight heparin is effective and safe in the treatment of acute coronary syndrome.It can increase the clinical effect,improve clinical symptoms and signs in the patients,and is worthy of clinical application.
